Abstract (en)

[origin: EP3779776A1] Embodiments of the present specification provide an abnormality detection method, apparatus, and device for unmanned checkout. In some embodiments of the present specification, a photographing area for unmanned checkout includes at least a depth camera of a detection area, and one or more people that enter the detection area can be detected by using image data obtained from the depth camera. Because the image data includes a depth image and an RGB image, and the detection area is an area for detecting a to-be-paid product, at least the depth image and the RGB image can be used to determine whether the quantity of the one or more people in the detection area is abnormal or the gesture of the one or more people is abnormal, and further determine whether to notify a central control system to stop product detection and trigger an alarm, so as to avoid a loss caused by an abnormality to a customer or a merchant.
